The Science Behind Orlistat - Why It Works
How Orlistat 120mg Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism called lipase inhibition. When you eat a meal containing fat, your body produces enzymes called lipases to break down dietary fat for absorption. Orlistat blocks these lipases, preventing approximately one third of the fat you consume from being digested and absorbed into your bloodstream. This unabsorbed fat passes naturally through your digestive system, reducing your calorie intake from dietary fat by roughly 30%.
Why Understanding the Mechanism Matters
Knowing how orlistat works helps you use it effectively. Unlike appetite suppressants that work in the brain, orlistat acts locally in your gut. This targeted action means it specifically addresses dietary fat without affecting other nutrients or your central nervous system. The medication works best when combined with a lower-fat diet - keeping meals under 15g fat each helps minimise side effects whilst maximising weight management benefits.

Proven Clinical Mechanism
Clinical studies demonstrate orlistat's consistent fat-blocking action. The medication inhibits approximately 30% of lipase enzymes in your digestive system, creating a predictable reduction in fat absorption. This mechanism explains why patients following a reduced-calorie, lower-fat diet see better results - the medication complements dietary changes rather than replacing them. Your prescriber will explain how this mechanism supports your individual weight management goals.
